The invention relates to shipbuilding, namely the swing-out columns, designed for installation on high-speed boats and serving to transmit torque from the engine to the propeller shaft and boat control. Column includes upper and lower gearboxes Z-shaped transmission, deadwood, propeller shaft, mechanism for reversing the propeller shaft. As the devices transmit torque angle used the CV joint, and Z-shaped transmission includes a vertical shaft torsioning type. The mechanism of the reverse of the propeller shaft located in the lower gears and provided with a slotted Cam clutch. System input channels of sea water includes a channel in the hollow stud that using the nut acts as a screed upper and lower gears, and the channel of the hollow studs communicated through made in her side holes with an internal cavity pump installed in deadwood column. The column is also equipped with a recoil buffer, which can be placed in deadwood and contain springs on the guide bolts. The invention allows to create simple and easy design, allow you to effectively manage the boat. 1 C.p. f-crystals, 7 Il.

the Chennai for installation on high-speed boats and serving to transmit torque from the engine to the propeller shaft and boat control.

Famous swing-out column containing the upper and lower gearboxes Z-shaped transmission, deadwood, the transfer device and the torque angle, propeller shaft, mechanism for reversing the propeller shaft and the input channels of sea water (see M. M. of Alwahab, C. N. Bochkarev. The engines of the boats. M , Shipbuilding 1985, S. 195-201).

The disadvantages of the known constructions is that for the transmission of torque from the engine to the column at the point of inflection of the upper horizontal shaft Z-shaped transmission axes of rotation and tilting of the column has a double cardan joint, which requires axial compensator, which complicates the design and increases the weight of the column.

The location of the reverse mechanism in the upper gearbox leads to premature wear and failure of all the gear and spline gear due to the inability to start the rotation with zero speed at the time of switching of the reverse.

System input channels of sea water does not provide cooling of the top of the gearbox and the engine.

In addition, when you return the column to its original position after hitting an obstacle possible mechanical damage as the elements of the column and feed elements of the ship.

TII simple and convenient construction, to effectively manage the boat.

This technical result is achieved by the fact that in swing-out column containing the upper and lower gearboxes Z-shaped transmission, deadwood, the transfer device and the torque angle, propeller shaft, mechanism for reversing the propeller shaft and the input channels of sea water, as the devices transmit torque angle used a CV joint, a vertical shaft Z-shaped transfer is made on the basis of the torsion, the mechanism of the reverse of the propeller shaft located at the bottom of the gearbox and is made on the basis of the splined clutch system input channels of sea water includes a channel in the hollow stud, linked through the side hole in the pin with the internal cavity of the pump installed in deadwood column, this column is equipped with a recoil buffer.

The recoil buffer is placed in deadwood column and contains the springs on the guide bolts.

System input channels of sea water includes a hollow stud 23, the channel which is divided by a crosspiece 24. Holes 25 channel studs connected with the internal cavity of the pump 26. With the help of nuts 27 pin 23 acts as a screed upper 2 and lower 4 gears. Channel studs 23 of the upper part is connected with the channel water cooling top gear 28.

The recoil buffer contains the springs 29, the guide bolts 30, the bar 31 and the stop 32.

Swing-out column is as follows.

The rotation from the flywheel when the engine 14 is transmitted to the upper horizontal shaft 6 Z-shaped transmission using the rubber coupling 15 and the 6 CV joint 13 allows torque to be transmitted in the position of the rotation and tilting of the column.

When reversing the movement of the lever 22 and rod 21 is vertical movement of the wedge 20, breaking into a horizontal movement of the rod 17, which in turn moves the Cam clutch 16 on the splines of the propeller shaft 5, thereby making the clutch Cam clutch 16 with Cams gears 11 (forward gear or pinion 12 (reverse). Return spring 19 through the pin 18 returns the Cam clutch to its original position.

Outboard water through openings in the housing of the lower unit 4 enters the channel of the hollow stud 23 and forth in the cavity of the pump 26, where under the pressure of the water enters the channel water cooling top gear 28 and is then transferred to the cooling of the engine.

When you return the column to its original position after hitting an underwater obstacle spring 29 buffer recoil soften the blow of the strap 31 on the stop 32, thereby eliminating the destructive consequences of the blow of the column on the stern of the ship.

Thus, the proposed design has the following advantages: the use of the Double as a device to transmit torque angle simplifies maintenance and Assembly of the column, increasing its reliability. Furthermore, the presence of Shrus eliminates move Horiz is in the prototype. The proposed device of the vertical shaft in the form of a torsion gives the opportunity not to require high alignment of the gears during Assembly and repair. The placement of the mechanism of the reverse of the propeller shaft in the lower gear improves working conditions gear, increases their service life, reduces vibroacoustic effect of time of switching the reverse. The location of the feed channel outboard water in the hollow of the pin associated with the internal cavity of the pump, gives the possibility to cool the top of the gearbox, in addition, the pin serves as the main screed the top and bottom gears. Buffer returns eliminates the possibility of serious damage when you return the column to its original position after hitting an underwater obstacle.
